' nYDnoPLANE-BOAT.

To all whom 'it may concern.

Be it known that I, WILLIAM HENRY FAUBER, a citizen of the United States, and a resident,I of Chicago, in the county of Cook and VState of Illinois, have invented certain new and useful Improvements in Hydroplane-Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had ';o the accompanyingl drawings, and to the characters of reference marked'thereon, which form a partV of this specification.

This Invention relates to improvements in that' class of water craft known as hydroplane boats which are lequipped with inclined surfaces or planes designed to act on the water when the boat is traveling at high s eed in a manner to lift the boat 'and lessen t e submerged area of the hull thereof, with consequent reduction of wave and skin resistance and the attainment of high speeds in prrportion to the propelling power employed. raft of this character heretofore )roposcd have the form of flat bottomed boats or boats provided with flat surfaces or planes designed to ride on or skim the top of the water. Such hydroplane boats when equipped with inclined surfaces or planes arranged as heretofore proposed, so far as .l am aware, are practicably available for use in smoothwaters only, for the reason, first, that in rough water the planes or surfaces by which the load is supported when the boat is'under high s 'eed are submerged by the wave action, where y is introduced a resistance which acts to retard thc speed of the boat; and, second, because the constructions heretofore proposed are not stable in disturbed waters and do notrespond promptly and accurately to the steering mechanism.

It is the object of my invention to produce a hydroplane boatwhich is capable of sucf cessful use underconditions of high winds and in seas more or less rough or disturbed and which is so constructed as to give great stability and carrying power to the boat and steering apparatus under such conditions. The invention consists in the matters hereinafter set forth and more particularly pointed out in the ap ended claims.

In the drawings igure 1 is a side elevay tion of a hydroplane boat made in accordance with my. invention.- Fig.- 2 is a horizontal sec-tion,- showing the Amain features of the Specification of Letters Patent. "Application :tiled January 28, 1907. SerialNo. 354,513.

Fig. 6 is a detail horizontal section, taken on ine 6--6 of Fig. 1. Fig. 7 is a partial side elevationof the boat, showing a modified form of device for -giving lateral stability thereto. Fig. 8 is a view of the boat in side elevation showing variations in several details of construction thereof. Fio'. 9 is Eig. s.` Fig. .1o is s detail, horizontal section, taken on line 10-1O of Fig. 8. Fig.. 11 is a detail closs-section, taken on line 11-1-1 of Fig. 8. Figs. 12, -13 and 14 are views in cross-section of the boat, showing different forms in which the hydroplane element may be made.

The illustration of my invention in the ac companying drawings is largely diagrammatlc, in order to clearly show the essential 'features of the invention, and for the further reason that the details of construction will vary in accordance with the dimensions of the boat, its capacity for speed and other conditions peculiar to any given vessel.

As shown in the drawings, 10 designates the hull of the boat which may be made of an whyat may be termed a keel attached to and extending downwardly from the hull, and 13 designates, as a whole, a'generally horizontal tubular member o en at both ends and attached to the hu Ithrough the medium of said keel portion and extending from front to rear of the boat. The downwardly facing surface of the upper part jof said tubular member constitutes the principle rhydroplane surface upon which the weight of the boat is carried when under speed, the said surface being at such time inchned u )wardly and forwardly to the horizontal. he said keel 11 constitutes the connection between the hull and the hydroplane member 13 and comprises, 'as herein shown, twoplates, laterally separated, in the middle and joined at their upper and lower edges to the hull and hydroplane member, respectively, thus constituting a hollow keel. So far as its connecting function is concerned, however, this part of the boat may assume other forms. The said hull, keel and hydroplane member kare made of any suitable rigid material, such as steel, bronze or the like and as light as practicable consistent with the required strength.

desired shape or material, 11 designates a cross-section, taken 15 designates a stern rudder of common form operating in the usual manner to direct the course of the boat. The post oi' the rudder extends into the hull for connection with anyl suitable form of steering mechanism motor' (not shown).

19 designates a generally horizontal'rud'- der at the stern oi the boat for regulating the inclination of the hydroplane member and consequentlythe lifting eli'ect oi' said hydroplane member when the vessel is under speed. A novel form of said rudder is herein shown, and will hereinafter be described.

20, 20 designate horizontal balancing rudders extending one from each side of the hydroplane member 'and connected therewith to rotate about transverse horizontal axes. The said balancing rudders are attached to hubs 21 which are pivotcd or rotativel mounted in the lateral walls of the hydrop ane member. The said rudders 2O are operated through the medium of arms 22 that are fixed rigidly to the pivoted hubs of the rudders and extend upwardly and are connected bv links or connecting rods 23 tion, thearms 22, 22

with contro ling means within the hull, whereby said rudders may be turned simultaneously and to an equal extent in opposite directions. As shown in Figs. 1 to 7, said operating arms are located outside of the hydroplane member and are curved to follow the curvature of said member.

As shown in Figs. 8, 9 and 10, the arms 22"` are located in spaces formed between the side walls of the tubular hydroplane member 13 and external' walls 14, 14, vwhich latter converge toward and are joined to the. body of the hydroplane member near the front and rear ends of the same. The spaces formed by the walls 14 14 communicate with the interior space ofthe hollow keel 11, and the arms 22 are located within said hollow keel and extend therethrough upwardly into the hull of the boat where they are connected by rods 23 with oppositely extending arms 24' on a rock-shaft 25 having a hand-lever'v 26 by which the same ma be turned for tilting the said balancing ru ders. In this construcare attached to the inner end of pivotal extensions of the hubs 21,

, 21 at points inside 'of the Walls 14, 14.

The said rudders. 20,. 20 are locatedat or near a horizontal plane passing through the axis of capacity the cylindric hyd roplane member, and are so disposed and connected to their actuating mechanism that they are parallel with each other when occupying a horizontal or neutral position, but assume opposing angles when rotated aw ay 'from their horizontal positions to balance the vessel, as indicated by lull and dotted lines in Figs. 1 and 8, so as to cause the vessel to right itselll in the water by giving turning motion-to the cylindric hydroplane member in either direction, as required. The lever connection shown in Figs. S and 9 is adapted to give opposite rotative movement to said balancing rudders, it being obvious that thc connection of the rods 23, 23 with the oppositely extending arms 24, 24 on the rock-shait 25 will result in the rudder being turned to an equal extent in opposite directions when said rock-shaft is actuated by the use ol' thc hand-lever 26.

27 designates a iin attached to and extending downwardly from the hydroplane meml.cr near its longitudinal center. The said iin aids to prevent rolling of the vessel under the eiiect of' waves and wind, and operates in connection with the balancing rudders to keep the hull upright. In small boats, the lateral balancing rudders 20 and the depending iin 27 are usually sufficient to keep the boat balanced or stable under ordinary circumstances. l t is evident that the connection of the said lateral l'lalaneing rudders with the sides of a cylindric hydroplane member, near the plane of the longitudinal axis thereof, is advantageous, inasmuch as the breadth gives great leverage to the rudders to hold the boat stable, and also because ,this location. of the rudders insures that they shall be submerged in a comparatively quiet body of'water under ordinary conditions of weather and sea. In some instances, however, and specially with larger size boats, it may be desirable to employ fixed or stationary, horizontal iins 28, suchl as are shown in Figs. 8, 10 and 11. Such Iins 28 extendlaterally from the hydroplane member and may be located either in front or rear of the movable balancing rudders 20 or both, at the front and rear thereof, as shown in said Figs. 8 and 10. Such auxiliary iins aid the hydroplane member in sustaining `the load when under speedand also aids to give lateral stability to the boat. AIn order to increase the of theY auxiliary stationary fins to lift the boat at hi h speeds, said iins may be curved downwar l`y at their rear ends, as

.shown in l? ig. 8.

The horizontal rudder 19 is designed to regulate the inclination of the hydro lane member or the depth at which the said hydroplane member 1s submerged in the water when the Vvessel is under s eed. The said rudder may be the ordinary Balanced type'of rudder,.but I have shown herein a peculiar and novel construction designed more espeend to a suitable support and is adapted toibe e Fig. 6. The transverse tends at-both ends outside the side plates of end by the atingdevice.

vWardly or downwardly ciali for use on light or small craft. ASaid rudder 19 is made of thin and flexible sheet metal and is fastened rigidly at its forward curved upwardly or downwardly at its rear action thereon' of a suitable oper- In adapting this form of rudder to the ty e of boat hereinillustrated, it is shown place below the rear end of the pen point surface and is centrally divided, giving 1t the form of two separate Hat lates or blades 29, 29, one located at each side of the propeller shaft bearin 18, as shown in Figs. 2, 5 and 6. Said rud er blades are attached rigidly at their forward ends to the central or keel extension 16. The free o i" rear ends of said rudder blades are connected with the rear ends of lever arms 30, 30 which are attached rigidly to the opposite ends of a transverse pivot shaft 31, mounted in the central fin or keel extension and to which is rigidly attached an operating lever 32. The said ever 32 extends forwardly and upwardly through the hollow keel, into the hull of the boat and is ll cated within the keel at one side of the propeller shaft, as shown in pivot shaft 31 exthe keel extensionand said arms 30 are connected at their`rear endswith the'rear or free ends of the rudder blades 29, 29. Any suitable form of attaching means may be ro- `vided between the rear ends of the ruder blades and the said arms 30, 30 of the'rudder. As shown in the drawin s, y said arms carr outwardly extending, rigid rods 33 that are slitted longitudinally'to receive the rear ends of said rudder blades. By reason of the rigid attachment of the forward ends of the rudder blades, as described, with the keel extension, and the connection at their rear ends with the arms 30, 30 on said rudderoperating lever 32, the swinging of said operating lever acts to curve the rear ends of said plates upthe blades on the Water, to effect the raising obliquely on its or depression ofthe stern of the boat, with consequent change of inclination of thehydroplane member to the horizontal, accompanied by corres ending variation in the lifting effect of sai(` hydroplane member. The rudder made as described is preferable, where it is capable of use, to an ordinary balanced indder for the reason ,that the deflecting or lifting ower of a curved surface is more efficient t an an inclined lane surface, relatively to the horizontal oice exerted in giving forward movement tothe boat.

Instead of making the cylindric hydroplane member of uniform 4dimensions throughout, it

underside on lthe front and rear thereof, along the curved lines 34, 34,

as shown in Figs. 1 and 8, thereby giving`to the endsof the. hydroplane members apand, by the action of vertical, laterally separated wa y ing from the lower margins of said is preferably cut away l Fig. 2.. Thus, when the' hydroplane is of cylindric at its ortion nearthe longitudinal center thereof? as indicatedat 35 in Figs. 1 and 8'.

A general advantage of the c lindric form of the hydroplane member is tiat this form form and cut away 4as described,

provides, in addition to the downwardl* facing or hydroplaiie surface, lateral'wal extending downwardly therefrom, which acty in the manner of horizontalv and. vertical centerboards to give steering control for depth and course. tion to the hydro )lane surface, consisting of the downwardly facing surface of the upper part of the hydro'plane member, the lateralv walls of said cylindric member, which aie always submerged, give stability, or lessened tendency lto roll, and also afford superior lateral steering control for directing the course of the boat, thereby enabling the boat to beveasily. steered in rough water under the influence of the course rudder.

It will be evident that the hydroplane member may be made of othei form Without departing fromthe spirit of the invention,

while maintaining the essentials of the hydroplane member before described, to wit,--

the downwardly facing load c arrying plane 01' surface and the lateral walls for giving stability and for steering control.

Fig.' 12 shows a semicircular hydroplane meniber the side walls 'of which may extend i below the axis or not., This soinicircular form is adaptable'where landings areto be made inshallow water. Fig. 13 shows a form of said hydroplane member consisting of a flat or horizontal top wall, forming the h droplaiie surface proper, and two latera ly separated, fiat, upright walls depending from the side .margins tliereof.- Fig. 14

shows the hydroplane member as sha ed to i wa s and s dependtop Walls. The cylindric form of the hydroplane member, however, possesses distinct advantages 'for the reason, first, that it is a stronger and more practical construction than a member wherein the lateral portionsor surfaces thereof aieiat or are not connected at the form two outwardly divergent to lbottom of the h droplane member, and .also lbecause said cy indric member is less ailected b the large wavesv in a rough sea than Hat ateral walls lwould be. .A further advantage of the cylindric hydroplane member is that the-balancing rudders 20, as well as the load carrying fins 28, 28, when the latter are employed, may be placed respectively at e complete cylinder form is retained only In other words, in addia greaterfdistance apart. thus increasing their leverage and their capacity to.mainta1n the boat' upright. l

The proportions or form of the hydrolane member may be otherwise varied. or instance, the rear end of the hydroplane surface may be curved downwardly, as indicated at 36 in Fig. 8, in order to obtain the maximum carrying capacity of the hydroplane surface at certain speeds. These are details, however, depending upon the character of the craft. i

A When* the boat is at rest in. the water, the hydroplane surface and keel are entirely submerged and. the hull is partially submerged.l and carries the load by displacement.

In starting the boat forward, the propeller is started giving the boat a forward impulse.

Either by ballasting the boat or adjusting the angle of the horizontal or depth rudder 19, the front end of the hydroplane surface isgiven an upward inclination and, as the boatgains speed, it rises by reason of the pressure of the water on the under side of the inclined hydroplane surface, as well as on the rudders 20, 2() and fins 28, 28, when the latter are used, until the said hydroplane surface is near the surface of the water and the hull and principal part of the boat is partially or entirely out of the water and, to a greater or less degree, free from the skin and wave resistance. While under speed, the depth to which'the hydroplane surface is submerged is regulated by the horizontal or depth'rudder 19, while the course of the boat is determined by the stern'or steering rudder-15. In order to maintain the boat in an upright position, the balancing rudders are operated as the conditions require, the said rudders being rotated to bring them -into opposing inclinations, thusv producing torsional' action on the hydroplane member in a manner to counteract tendency to roll or tip under the action of wind or waves on the hull and to'thereby 4maintain the boat upright. The ressure of any side wind and waves may e partially neutralized by inclining the boat in that. direction to an angle affording the desired result without producing undue resistance to forward motion lnder the resistance of the balancing lruders.

In some instances l may employ a vertical balancing rudder 37, as shown in Fig. 7, in-

lieu of the lateral, horizontal balancing rudders 20, 20, before referred to. ln such instance, said rudder will be arranged to turn on a vertical axis and may be located be'- tween the hull and hydroplane member, either in an opening in the keel 11, when the keel is made continuous,or inthe space between the hnll and hydroplane member, in

l'case the hydro )lane member is connected with the hull ot erwise than by a longitudinally continuous keel. This type of balsite direction.

below the bottom thereof.

ancing rudder operates to produce the same general result which is gained by the balancing rudders 20, 20 having the effect, when turned at an angle to the line of the keel, of tipping or inclining the hull to one side or the other in order to counteract any tcndency of the hull to roll or swing in the oppoyThe upright balancing rudder 37 may be employed with a lighter craft and has the advantage of being very readily ap lied and easily operated.

tis to be noted that the hydro )lane meinber shown in Fig. 8, and the balancing and lifting or deflecting fins 28 have in common the feature of a downward curvature at the rear end thereof, while the horizontal ru d der is adapted to be curved either upwardly or downwardly at its rear end. An .advantage is gained in makin a lifting or dellecting surface curved at tie rear end thereof, for the reason that the lifting or dellcctng c'll'ect is greater with such a curved surface than with a flat or plane surface relatively to the horizontally exerted or propelling force employed. Manifestly, the said fins 2S and rudder 19, as well as the hydro )lane meinber 13, equally constitute hydrop anos, inthe general sense of that term and l therefore desire to'cover such curved'form in a deflecting or lifting surface whether applied to allori* zontal rudder, to a deflecting and balancing lin, or other like partfor to the main lifting member or members of a hydroplane boat.
